Vith the valves 19, 25 and 27 open and the valves 16, 22 and 29 closed,the flow of steam is in the direction indicated by the dotted arrows inFigure 7, namely through the valve 19, evaporator 11, separator 13,evaporator 10, separator 12, and thence outward through pipes 80 and 31.

An alternative form of baflie drain for use in the separators is shownin Fig. 4, in position for use. This modification consists of a metallicplate 42 having inclined projecting or protuberant ridges of baffles 43and an inclined flangelike trough 44 adapted to guide the descendingfluid into a central drain pipe 45 which in turn discharges. into theoutlet pipe 41. Ribs or flanges 46 at the edges are also desirable toassist in trapping the liquid which is entrained by the steam. A passage47 similar to passage 39 of baffle drain 35, is

provided for the upward escape of steam in the rear of the battle drain42.

By the construction and arrangement shown itis possible to utilize themaximum capacity of the apparatus to the greatest ad-' vantage and byreversing the direction of the flow from time to time to keep theappara- 'tus from fouling.

The separator is simple in construction and easy to install or remove asnecessity may require.

I claim 1. Apparatus of the character described comprising a separatortank having an inlet at one side and an outlet at the other side, saidtank also having an outlet at the top and a drain outlet at the bottom,a baffle plate mounted transversely in said tank and extendingvertically beneath the outlet in the top and having vertical ridges onits opposite sides and an inclined drain at its lower edge and a drainpipe secured to the lowest part of said drain. 1 i

2. Apparatus of the character described comprising a separator having aninlet at one side and an outlet at the top and a baffle plate arrangedto cross the separator leaving spaces around the side edges and aroundthe bottom, said bafile plate having at its side opposite the inlet andat its upper end an outlet to register with theoutlet at the top of theseparator.

3. Apparatus of the character described comprising a separator having alateral inlet and a detachable cover with an outlet, and a bafiie platesecured tosaid cover and havlng on the side opposite said inlet anoutlet registering with the outlet in the cover.

4. A separator of the character described comprising a separator tankhaving an inlet at one side and an outlet at the other side, said tankalso having an outlet at the top between said inlet and outlet and adrain outlet at the bottom, a baflie plate mounted transversely in theupper part of said tank and extending drain outlet at the bottom, abaflie plate extending transversely of said tank between the openings,said baiile plate having on its opposite sides marginal and spacedridges, said baille plate also having an inchned trough at the loweredges and a vertical pipe for draining liquid from said baffle plateinto said drain outlet of said separator tank.

6. A separator comprising a casing having an inlet at one side, anoutlet at the opposite side and an auxiliary outlet and an elongateddrain outlet at the bottom, a baffle plate sup ported between the sideinlet and side outlet to intercept liquid from the inlet and a drip pipeextending from the bottom of the baflle plate to a point near the bottomof the casing.

7. A separator comprising a casing having a detachable cover with anoutlet, and having inlet and outlet openings on opposite sides, a baflleplate secured to and removable .with the cover and extending down intothe casing between the side inlet and outlet openings, and having itsedges spaced apart from CHARLES W.
